Structure designs, and can enhance the feel of needle tubing when in use, and operator is made to have better operating experience.
A kind of application method of above-mentioned surface layer anesthesia needle tubing, includes the following steps：
1) fixed cylinder is rotated, fixed cylinder is removed from connecting cylinder；
2) card left end is pressed down on to level, makes card no longer seized piston bar；
3) connecting cylinder is put into the vessel for filling anaesthetic, handle is caught to drag upwards, anaesthetic is taken out
It takes, anaesthetic is made to enter in cylinder；
4) after the completion of extracting, card is unclamped, so that card left end is moved up under the action of the second compressed spring, to press from both sides
Tight piston rod；
5) fixed cylinder is taken out, rubber sprinkling shield is arranged in fixed cylinder, then fixed cylinder is mounted on connecting cylinder；
6) thread bush is rotated, so that inverted L-shaped ruler plate is moved up, the position indicated on graduation mark according to inverted L-shaped ruler plate lower end
Set the usage amount of determining anaesthetic；
7) cylinder is held on the other hand, and rubber sprinkling shield pressing in the position for needing progress epidermis anesthesia, another hand is pinched
Handle and flexible handle are fastened, so that fixed handle and flexible handle left end is moved toward one another, at this point, compression bar squeezes tabletting, makes pressure
The horizontality of piece shifts, simultaneously because the fourth hole of tabletting upper surface right end is clearance fit with piston rod, works as pressure
After the horizontality of piece shifts, tabletting can be moved down by fourth hole clamping piston bar at this point, piston rod has
Trend overcome clamping force of the card to piston rod to drive card left end that there is the trend that moves down, continue to clutch solid
Determine handle and flexible handle left end, you can so that piston rod is moved downward, band piston moves down, to make the anesthesia in cylinder
Drug is sprayed from drug spray orifice under the effect of piston, is anaesthetized to epidermis；
8) flexible handle is unclamped, the first compressed spring resets under the spring potential energy effect of itself at this time, pushes tabletting right
End moves up, since the first compressed spring is arranged on the piston rod, after the extruding for unclamping the first compressed spring of tabletting pair, and first
Compressed spring provides a power straight up to tabletting, so that tabletting is unclamped the extruding to piston rod, to make tabletting reset, together
When drive flexible handle to reset, piston rod has the trend that moves up at this time, to drive card left end to upwarp, makes the 5th logical
Hole completes to set the card of piston rod again, and piston rod is avoided to move up；
9) fixed handle and flexible handle are clutched again, so that the anaesthetic in cylinder is carried out secondary injection, until screw thread
Set lower face withstands on top plate upper surface；
10) anesthesia syringe is taken away, anesthesia is completed.
Using the invention of above-mentioned technical proposal, in such a way that rubber sprays shroud cover in patient's epidermis, to control anesthesia
Range can choose different size of rubber sprinkling shield according to use demand for different anesthesia scopes in actual use
Cover, and rubber sprinkling shield is detachably connected with fixing sleeve in the present invention, it is convenient to replace, and solves traditional anesthesia outfit anesthesia
The problem of range is unable to control, while shield is sprayed by rubber, site of anesthesia is covered, the volatilization of anaesthetic can be reduced, i.e.,
The usage amount for reducing anaesthetic also reduces the influence of the medical staff after anaesthetic is volatilized by air；It is extracting
When anaesthetic, fixed cylinder is first removed, the connecting cylinder by aperture size much larger than drug spray orifice extracts anaesthetic,
Reduce extraction difficulty；Meanwhile anesthetic liquid medicine is placed in cylinder, by adjust thread bush lower face and top plate upper surface it
Between distance, and showed by the position that inverted L-shaped ruler plate lower end is on graduation mark, accurately control anesthetic liquid medicine in rubber
Glue sprinkling shield shrouds the anesthesia dosage in range；Thread bush is rotated again, thread bush is made to move up, then rubber is sprayed and is protected
Cover is placed on other positions for needing to anaesthetize, you can anesthesia is re-started, it is easy to use, and fiber crops need not be perfused in cylinder again
Liquor-saturated drug simplifies operating process, reduces operation difficulty.
